Maen Greenwich 38 GMTvsMarathon JDD (Jumbo Day/Date) Anthracite Diver's Automatic
The numbers, the dial colors, the calibers — laid out so you can stop flipping between tabs.
Owners + reviewers, side by side
Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
Owners and reviewers widely praise the Maen Greenwich 38 GMT for its elegant 38mm sizing, exceptional case finishing, and flawless enamel dial. The SwissTech S24-045 movement is noted for its smooth winding and accurate timekeeping, with figures ranging from zero deviation to +7 seconds per day, though its 40-hour power reserve is considered unremarkable. Some owners find the hour markers too bold, the GMT hour markings difficult to read, and the GMT hand alignment slightly off, while one user experienced crown resistance and movement stoppage. The lug-to-lug measurement is reported to make the 38mm case wear slightly larger. Overall, owners and reviewers rate the Maen Greenwich 38 GMT highly for its premium finishing and design at its price point.
Owners widely praise the Marathon JDD (Jumbo Day/Date) Anthracite Diver's Automatic as a tough, underrated tool watch with lifestyle appeal, highlighting its robust build and tritium lume for excellent legibility. However, its 46mm size is a common criticism, with some finding it heavy and top-heavy, and the OEM rubber strap stiff. One owner noted the watch runs about 10 seconds fast after three days, and the ETA 2836-2 movement offers approximately two days of power reserve. On balance, owners and reviewers rate the Marathon JDD (Jumbo Day/Date) Anthracite Diver's Automatic highly for its robust tool-watch build and legibility, despite its substantial size.
